TO ALL WHOM IT MAY CONCERN:

Be it known that I, HENRY W. H0\\"LAND,'of Calhoun, in the county ofRichland, and State of Illinois, have invented a new and improvedRevolving Churn; and I do hereby declare the following to be a full,clear. and exact description of the same, reference being had to theaccompanying drawiugs,'whieh are made part of this specification.

My invention consists, first, in a simple arrangement for imparting acontinuous rotary motion in contrary directions to the" dash-rod andcream-vessel without passing either shaft through the bottom of saidvessel: second, in a novel construction of dasher; third, in anarrangement for forcing the air 'down into the body of the cream andallowing its escape therefrom. and in the provision of slides or valvestoregulate the amount of air thus forced in. In the drawings- Figure 1is a longitudinal section on the plane indicated by the line .2- Q7,fig. 2.

Figure 2 is a horizontal section on the line y 1/, fig. 1. Q T

Figure 3 is a plan view of the top of the cream-vessel.

Figure at is a transverse section of the same on the line 2 z, fig.

A represents the frame, which may be of any suitable construction, toform bearings for the shafting, the preferred form being represented. 13is an upright shaft journalled in bearings a a, and having,respectively, at its top and bottom, the crank-wheel C and pulley D, thelatter of which is connected by the cord or band E to the pulley F onthe upright shaft F. This shaft is journalled at a a, and supports onitssquare upper end the disk G, on which the cream-vessel H rests, itbeing held on it and prevented from rotating separately therefrom by thepins or brackets g, three or more in number, which grasp its peripheryand firmly hold it on its supporting disk. This vessel is provided witha cover, H, having holes I: through it, which are covered by flaringcaps It, by which, as the vessel revolves, air is forced through,theholes into the cream, and slides or valves 71 by which the amount ofair thus admitted is regulated. The cover is also provided with a pipe,it, for the discharge of the surplus air thus admitted. It has also acentral opening, 71, through which the dashshaft passes, its entrancebeing permitted by a dove-tailed slit filled by the dove-tailed slideit". This slide is provided with a handle, ii, to facilitate itsremoval, and is held, in place by the sides of the vessel II when in 1use. I is the dash-shaft, which is supported on the pivot 74" in thebottom of the vessel H, and by the bearing in the frame A. This shaft isprovided with a. pulley, J, which is connected by the belt K to thecrank-pulley C, the motion imparted being in an opposite direction tothat of the cream-vessel, the belt or band by which it is rotated beingcrossed so as to reverse the motion. L represents the dasher, which isprovided'with oblique perforations Z, which, in rotating, have atendency to throw the cream upward and outward against the rim ll, andits periphery is provided with a metallic strip, Z, of sufficient widthto form a flange abovc and below it, which flanges are nicked and bent,as represented, so as to form a number of oblique wings, the under onesacting to throw the cream toward the centre, and the upper toward theperiphery of the vessel, and thus throroughly agitate it and break itsglobules.

Having thusdescribed my invention, what I claim therein as new, anddesire to secure by Letters Patent, is

1. The holes 71, flaring caps k, valves or slides 7: and discharge pipeIt", in combination with rotating churn, substantially as and for thepurpose set forth.

2. The dasher L, constructed with oblique perforations l anddouble-oblique serrated periphery 7, in combination with the revolvingvessel H, substantially as and for the purpose specified.

3. The arrangement of the upright shafts B F l, crank-wheel C, pulleys DF J, belts or bands E K, and vessel H, substantially as described. l 4.The dove-tailed slide 71 in'combination with the dove-tailed slitted lidH and vessel H, substantially as and for the purpose set forth.

To the above specification of my new and useful improvement in revolvingchurns I have signed my hand this 11th day of July, A. D. 1867.
